Similar to withoutExceptionHandling and withExceptionHandling, these two test helpers allow developers to quickly unbinding and rebinding Laravel Mix in the container during testing.

This behavior was added in #26289, but still requires intimate knowledge of the underlying Mix class and proper binding function. Furthermore, it adds a relatively obscure, big block of code for a simple need.


$this->swap(\Illuminate\Foundation\Mix::class, function () {
    return '';



Note: Inline with other TestCase methods, withoutMix returns the instance allowing it to be chained with other fluent methods, e.g. $this->withoutMix()->withoutExceptionHandling()->get('/');

Would be cool if we could somehow implement something that disables mix all together for all tests. Like calling this method in the setUp method of the TestCase class.

This has proved necessary in a project I just took over with "six mysteriously failing unit tests that pass on our locals." It would have been super helpful if this was documented on
